1,047,884. Original application filed June -3, 1907,

To all whom it may concern:

Be it known that I, ArwELL J. BLACK- FORD, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in OileBurners, of

- which the following is a specification, reference-being had therein to the accompanying drawing. j f This invention relatesto improvements in oil burners, and is'a divison of my application filed June 3rd 1907, Serial No. 377,057, and the present invention pertains toan improved flame and ,air deflector so con- ;structed that the radiant heat from the flame is intercepted and prevented from impinging on the metal parts, engaging with x-itheyflame, through a passage so arranged and adjacent to the inner edge of the wick,

.thus contrilniting to a lower temperature in these parts while at the same tune the inner edge of the wick is ventilated so that any vapor. generated at'this point is carried to that. flame cannot travel or persist therein. These combined, features insure a persistent lowering of the temperature about the inner edge of the wick.

This invention is applied to the wick typ f burner in which the vapor is generated or evolved from the outer surface of the wick. In thiswick-type of burners the vaporizing point is the upper end or exposed portion of the wick, and the amount of vaporization that occurs is-dependent upon the 351 amount of heat to which the exposed portion of the wick is subjected. This heat is furnished'by the flame burning adjacent to the exposed portion of the wick and the volume of vapor generated is dependent upon the amount of heat communicated to the wick contact with the metal. part closely adj ametal flange above, which have such a cool- Specification of Letters Patent.

ing' effect on-the match flame as to make it commercially impractical to ignite thewick,

The object of the present invention is to provide the wick engaging metals and inner portion ofthe wick with a measure of protection against the radiant-heat from the body of the flame, and also prevent the .flame from burning in proximity to these parts.

Patent-ea Dec.-17,1912.

Serial No. 377,057. Divided and this application m s rn'is, 1908, Serial No. 426,831.

Theaccompanylrig drawing'is a vertical central sectional view of my improved combined deflector, radiant heat interceptor and temperature controller.

Referring now to the drawings, 1 is the inner wick tube, :2 the wick and 3 the outer wick tube, which-has its upper end deflected inward against the wick as shown at 4.

My improved deflector, heat intercepter and temperature controller 5, is vertically movable upon a rod 6, and the lower end of this rod is firmly connected with the inner wick tube 1, bymeans of a suitable bracket or spider 7. This improved deflector is provided'with a flange or sleeve whichprojects upward beyond the inner wick tube, and is provided with a peripherally projecting wick engagingflange9, which rests upon the upper end of the wick as shown. The engagement of the flange 9 I with the wick J causes the deflector tobe raised and lowered with the wick as it is adjusted.

The present improvement is the combining with the wick, its wick tube and the said flange 9, of a peripheral outwardly projecting flange 10 carried by the deflector, and which as shown inthe drawing is so near to the flange 9 as to form with it an air passage so narrow that flame cannot persist in it. The flange 10 should be disposed in a substantially horizontal position, so that not only will it form a flame excluding passage but will be an intercepting 'plate or shield,

to'prevent the radiant heat of the flame flows outward between the flanges 9 and 10.

From this arrangement and constructionit will be observed that the projecting flange 10 is so near the flange 9 that it not only intercepts the radiant heat from the lower terior of the portion of the flame and constitutes a flame excluding air-passageand thereby controls the temperature .of the wick and its engaging. metals, but also provides a currentof cool air coming from the interior of the butin any case the wick flange and the pro-' tecting flange should be so arranged as to leave an air-passage 12, as this arrangement not only lessens the heat which may be imparted to the wick from the lower flange, by the action of the protenting flange in intercepting and shielding the lower flange and top of the wick from the heat radiated from the body of the flame, but the protecting flange also provides that the wick flange and passage-way t rou which air from the inli urner may flow to positively maintain the ower flange and the exposed portion of the wick at a lower temperature. It has been found in practice that; by making the upper flange wider 'or narrower, it exhibits-a greater or less shielding'influence on the lower flange, so that with a given wick exposure and a certain grade of oil, the vaporization from the exposed wick will be greater with a narrower flange'and less with a wider flange, whereby it is possible, by making a protecting flange so positioned in respect to the wick flange and thewick exposure and of proper width, to provide a large wick exposure, but still with the use of light oils, having a maximum flame that is safely below the smoking point.

The rod 6 passes loosely through a tube 14,

depending from the top15 of the deflector, and a detachable stop 16 carried by the upper end of the rod 6,serves to limit the upward movement ofthe deflector, and thereby the upward movement-of the wick.

I am aware that-deflectors have heretofore been provided with a plurality of pcnot protect the wick flange, the exposed portion of the wick and the metals engaging the wick, from becoming so heated as to produce an excess amountof vapor and consequent suioky flame.

Having thus'described my invention, what I claim and desire to secure by Letters Patent is: I

In a wick burner, the combination with a vapor generating exposed portion of the wick, of an air deflector comprising a sleeve extending above the upper end of the wick, a flange secured to said sleeve and extending over the top of the wick and forming a stop for the wick, and a radiant heat intercepting flange secured to the sleeve above and in such position to the first mentioned flange as to shield it from the radiant heat of the lower part of the flame and thereby producing a blue flame, substantially as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
